What are you guys setting your SOC to while there isn't that much loadshedding? Did you change it to lower your electricity bill?

Tried to set it based on my usage different % based on time.l lowest I allow it to go is 25%.

Didn't change it based on loadshedding though been set like this to try and get most out of my investment

I try get ours full by 15:30 and have the inverter set to use grid from 15:30 until 06:00 with minimum SOC set to 60% for unforeseen issues and because we are only making around 25kWh/day from solar at the moment.

20% (I have 15kWh battery storage). Reached 20% a few times, during winter when there has not been enough sun. However, I see that the sun has been better since the beginning of July and my batteries are reaching 100% again.

12%

Had mine sitting in backup mode at 100% since the bad weather started. I'll changed it back when the weather passes.

My setup is 8kW Sunsynk inverter and 10kWh Volta battery. Worked flawlessly since Oct '23. I would appreciate some help both determining what happened and changing settings if needed. Last night all went suddenly dark at around 20h30, checked the system and discovered grid power was lost at around 19h00 at which time SoC was
40%. System mode setting for that time period was 28%. Logged the call with the City of Cape Town and the guys came and restored grid power - seems like a trip in the street box. But, what I want to know is why the battery full discharged?

SOC system mode setting is only applicable when there is grid to take over when you hit that SOC percentage. Because you lost grid, your system continued to run off battery until your shutdown SOC value was reached.

I gather your shutdown value is set to 0% because that is how low the battery SOC went to. If your shutdown value is set higher than 0%, then you have a battery issue at low SOC because the system should have switched off at the shutdown SOC value.

I can't see the consumption values but why would it go from 25% SOC to 0% within minutes with no significant change in consumption. That would concern me.

Thanks @FlashSA. These are my battery settings. So there seems to be a problem.

Hi @AchmatK. I’m not sure what to make of time scale on the graph. Jumps from 20h00 to 23h40

This drop of from ±28% to zero is what would concern me as you consumption was pretty stable at the time.

Yes, looks like a similar issue I was having when one of my Hubble's had a faulty cell - sudden SOC drop.

Yip, you should've been in the dark at 15% and stayed at 15%. Possible faulty lithium cell - see my previous post.

Hi All

Having a weird issue today, my power tripped when my wife used the microwave. Upon investigating the db boards, nothing has tripped. However, the green light by the combiner box next to the changeover switch is off.

Changeover to grid works fine, light comes back on and power is back. But when i switch back to inverter, the light stays off. Could this be a fault changeover switch? How does one tell?

Post a pic of said changeover

any DB switches before the inverter - push them down and up again
Seen many cases where switches look like they up but are actual down (especially Earth leakage ones)

I got someone to come out and it was a faulty changeover switch. The switch had a brown stain next to it when we removed it. apparently happens alot.

Anyone noticed their SOH has dropped - year into owning system, which is normal.

Brown stain you say
so $h1t happens

I'm down to 95% SOH, after 2 and a half years of running. Pylontech batteries.
